Answer:
80 degrees
Step-by-step explanation:
both intersections are the same, so we can count them as one. We notice that one line is a straight line compared to other so we can subtract 100 from 180 and get 80
10.
5 multiplied by 2 "5 x 2" = 10
Answer:
9
Solution:
Write it in an algebraic form (x is your number)
2x-11=7
Now solve
2x=7+11=18
X=18/2=9
3cd^2(6cd + 14cd^2)
18cd^3 + 42cd^4
